Question about 2001 Mercedes-Benz S-Class
The system is charged. Have recovered, vacuumed and charged the system multiple times. High and low side lines are hot. Compressor is engaging. 2.10 lbs freon, 90 - 100 psi. No codes are showing on my scanner (Genisys - system 3.0). Any help would be great.
I think that this might help you. The a/c compressor is a continuos running type there is no clutch. It has a wobble plate internally wich changes the piston stroke. Screw the genises machine-it is probably only reading a partial on the climate control module. see if you can find the self diagnoses diagram either from the factory or if you have all data. you can pull the codes right from the unit itself and they will be accurate. If you can,t pull codes see if you can get an actual value of the sensors in the a/c unit. You should be able to pull that up as well if not try the genisis. Look very closely at you evaporater sensers(left and right) you will probably see a -40 degrees-that is the sensor default input reading when the sensor goes open. That sensor is used to moniter the wobble plate position of the compressor.
